讲座内容:

Symmetry and topology, as the two fundamentally important concepts in physics and mathematics, have not only manifested themselves in science, but also provided us with profound understanding of various natural phenomena. In this talk, I will first introduce our theoretical work on topological gapless systems, including mainly time-reversal and specetime-inversion symmetric topological metals/semimetals [1-3]. Then I will report experimental realization and manipulation of several topological semimetal bands in superconducting quantum circuits as well as the detection of exotic topological characters in these systems [4-5].
